Describes all the possible remote diagnostics tests that you can run on an Edge to obtain diagnostic information. The diagnostic information contains Edge-specific logs for analysis.
Remote diagnostics test can be run from the VMware SD-WAN Orchestrator by selecting the SD-WAN Edge and choosing Test & Troubleshoot > Remote Diagnostics, selecting an individual diagnostic test, and then clicking Run .

LTE SIM Switchover
For 610-LTE devices only, run this test to switch active SIMs. Both SIMs must be inserted to run this test. The test will take approximately four to five minutes.
After the test is successful, you can check the status of the current active interface in the SD-WAN Orchestrator under the Monitor -> Edges - > Overview tab.
List Active Firewall Sessions
![](images/GUID-8FB5DDE1-999F-40DC-B40E-DAE93D35AD0F-low.png)
- LISTEN - represents waiting for a connection request from any remote TCP and port. (This state is not shown in a Remote Diagnostic output).
- SYN-SENT - represents waiting for a matching connection request after having sent a connection request.
- SYN-RECEIVED - represents waiting for a confirming connection request acknowledgment after having both received and sent a connection request.
- ESTABLISHED - represents an open connection, data received can be delivered to the user. The normal state for the data transfer phase of the connection.
- FIN-WAIT-1 - represents waiting for a connection termination request from the remote TCP, or an acknowledgment of the connection termination request previously sent.
- FIN-WAIT-2 - represents waiting for a connection termination request from the remote TCP.
- CLOSE-WAIT - represents waiting for a connection termination request from the local user.
- CLOSING - represents waiting for a connection termination request acknowledgment from the remote TCP.
- LAST-ACK - represents waiting for an acknowledgment of the connection termination request previously sent to the remote TCP (which includes an acknowledgment of its connection termination request).
- TIME-WAIT - represents waiting for enough time to pass to be sure the remote TCP received the acknowledgment of its connection termination request.
- CLOSED - represents no connection state at all.

Multi-hop BGP Routes
Over Multi-hop BGP, the system might learn routes that require recursive lookup. These routes have a next-hop IP which is not in a connected subnet, and do not have a valid exit interface. In this case, the routes must have the next-hop IP resolved using another route in the routing table that has an exit interface. When there is traffic for a destination that needs these routes to be looked up, routes requiring recursive lookup will get resolved to a connected Next Hop IP address and interface. Until the recursive resolution happens, the recursive routes point to an intermediate interface.

- It should be a connected route IP
- It should be reachable and the routes should be advertised
When the Edge cannot select a valid IP as the Source IP to initiate the tunnel request, the VPN Test will fail with the following error.
Branch-to-Branch vpn is disabled. Please enable it before running the test
WAN Link Bandwidth Test
![](images/GUID-C1E2A2A6-F28C-4ECE-8FD4-717D0364CC92-low.png)
As the bandwidth test is run when the tunnel reconnects after a period of instability, there have been occasions in the field where the link has recovered enough for tunnel connectivity, but not enough to accurately measure the bandwidth of the WAN link. To address these scenarios, if the bandwidth test fails or measures a significantly reduced value, the last known “good” measurement will be used and a re-test of the link will be scheduled for 30 minutes after the tunnel is established to ensure a proper measurement.
